For this module, you will investigate the operation of antennas.  Antennas can both transmit and receive electromagnetic waves.  You see antennas everywhere from portable radios and cell phones to radio transmission and cell network towers.  In this laboratory, you will look at two types of antennas, a Linear Antenna (End-Fed) and a Linear Antenna (Center-Fed). […]

Turn in your answers to the following problems below.  As always, make sure to show all of your work.1.  The so-called “hydrogen alpha (Ha) line” is a specific wavelength of red light caused by excited atomic hydrogen.  It is frequently used when studying the Sun.  The wavelength of Ha is 656.3 nm, or 656.3*10-9 m.  The […]

SCI202 – Applied Physics II Module 4 – SLPLight        For this module, you will investigate the phenomenon of refraction.  The simulation allows you to experiment with changes in the angles of incidence and combinations of materials.  Do the following:Click on the following link to access the simulation (number 5 on the list of required readings and resources: see […]

Turn in your answers to the following problems below.  As always, make sure to show all of your work. 1.  Sound waves travel through an aluminum bar at a speed of 1400 m/s. If the frequency of the sound wave is 1000 Hz, what is the distance between crests on a sound wave traveling through aluminum? […]

The simulation at the source below  (number 4 on the list of required reading and sources; see the Background Materials for this module) allows you to experiment with many of the variables that produce sound when an object is hit or scratched.  The website contains a good explanation of the variables, which include hardness, base frequency, […]

Turn in your answers to the following problems: 1.  (Rev 9/11) Two alpha particles, each with a charge of 3.20*10-19 C, are one Ångström (1 x 10-8  cm) apart, in vacuum.  What is the electrostatic force acting between them, in N?  Is the force attractive or repulsive? 2. (Rev 2/11) If the force acting between two electrons (each […]

    Hello! I am looking for help on a final exam. I am only able to log in once to the exam. I can provide the questions as soon as I accept a handshake. It will be some multiple choice and some essay questions. The essay questions must be answered providing references in APA format. […]

  For this module you will run a simulation of Lorentz force exerted on a current carrying conductor located in the magnetic field of a horseshoe magnet.  The experiment is set up so that you can change the direction of polarity of the magnet and the direction of the current as well as turn the […]

The painter Mary Cassatt is often discussed as an American artist who, at the end of the nineteenth century, became intimately involved with the European Impressionists and strongly recommended them to American collectors. Her work often focuses on the depiction of informal domestic life. Compare the domestic scene featured in her Mother and Child of […]
